|•||Token names must be unique.|
|•||You can only define tokens with a single translation; you cannot define mixed source tokens. For example you cannot define a new token which has a translation of "weekday" or "week-end" depending on the date, because Q++ has no way of knowing which of the 2 translations to use.|
|•||The first character of any user defined token must be ':' (a colon).|
|•||The characters allowed in a token name are the following : 'a' to 'z', 'A' to 'Z', '1' to '9' and the characters '&' ':' '.' ';' '!' '\' '/' '(' ')' '|' '_'.|
Note that you will be warned if the new token name violates any of the rules above.
